Lately, I've been seeing a lot of spam along the lines of:
Subject: man, who filmed this thing? If your dad sees this video you made, he is going to kill you. Go look at it: http://www.youtube.com/......
Then the youtube link goes off to a IP-based website, no doubt to install some spyware or something. I certainly didn't click it.
Can you imagine how many kids will see this email, think “Oh shit, who had a camera at that last party…” and click the link?
